Diagnosis

Andrena flagrans sp. nov. can be placed in the subgenus Planiandrena Osytshnjuk, 1983 because of its very broad process of the labrum ( Fig. 88 ), narrow foveae that tightly follow the inner margin of the compound eye ( Fig. 87 ), broad and finely shagreened propodeal triangle with weakly indicated lateral margins, shiny terga ( Fig. 90 ), hind tibial spur that is slightly broadened submedially, and pygidial plate with slightly raised central area. The subgenus was described from four Central Asian species ( Osytshnjuk 1983a), but it reaches to Israel ( Pisanty et al. 2022a). Andrena flagrans differs from Central Asian taxa because the clypeus is convex (not flattened or depressed) and is most similar to A. veterana Pisanty, 2022 and A. huma sp. nov. (see below for separation from this species). Andrena flagrans can easily be separated from A. veterana because the terga are entirely shiny ( Fig. 90 ), without shagreen, discs impunctate (tergal discs of T2–4 basally shagreened, sparsely and very finely punctured) and the propodeal triangle lacks short raised longitudinal rugae along its basal margin (propodeal triangle with short raised longitudinal rugae).

Etymology

From the Latin present participle ‘ flagrans ’, meaning ‘burning, blazing’, or ‘shining’, in reference to the strongly shining terga.

Description

Female

MEASUREMENTS. Body length 10 mm ( Fig. 85 ).

HEAD. 1.2 times as wide as long ( Fig. 86 ). Clypeus dark, weakly domed, laterally with large shallow punctures, punctures separated by 1–2 puncture diameters, centrally becoming sparser, separated by 3–4 puncture diameters; clypeus centrally with wide longitudinal impunctate line, becoming wider apically, apical third of clypeus without punctures ( Fig. 87 ). Clypeus surface laterally and basally shagreened, becoming weaker apically, apical half of clypeus smooth and shining. Process of labrum short, broadly trapezoidal, four times as wide as long, covered in fine latitudinal wrinkles ( Fig. 88 ). Face, gena, vertex, and scape with long whitish hairs, longest equalling length of scape. Gena equalling width of compound eye; ocelloccipital distance small, ½ diameter of lateral ocellus. Foveae narrow dorsally, occupying ⅓ of space between compound eye and lateral ocellus, narrowed slightly below at level of antennal insertions; filled with light brown hairs. Antennae dark, A3 exceeding A4+5, slightly shorter than A4+5+6.

MESOSOMA. Scutum and scutellum laterally shagreened, weakly shining, shagreen weaker centrally, here shining more strongly; surface irregularly punctate with shallow punctures, punctures separated by 1–3 puncture diameters, sparser centrally ( Fig. 89 ). Pronotum without humeral angle. Mesepisternum with fine granular reticulation, weakly shining, covered in faint extremely shallow punctures with poorly defined margins. Internal part of propodeal corbiculae with fine granular reticulation, weakly shining. Propodeal triangle broad, not structurally delineated laterally but very slightly depressed, basally with very small and faint raised rugae, elsewhere with granular shagreen, weakly shining. Dorsolateral faces of propodeum with stronger shagreened, duller, propodeal triangle therefore defined by change in surface sculpture. Mesosoma with long whitish hairs, sparser dorsally, longest equalling length of scape; propodeal corbicula with weakly plumose hairs dorsally, inner surface with long simple whitish hairs. Legs dark, basitarsi and apical tarsal segments progressively lightened orange, pubescence whitish. Tibial scopae white with few brownish hairs dorsally at base, femoral scopae and flocculus white. Hind tarsal claws with inner tooth. Hind tibial spur slightly broadened submedially. Wings hyaline, stigma and venation orange, nervulus interstitial; first recurrent vein enters second submarginal cell beyond its middle.

METASOMA. Terga dark, marginal areas of T2–4 very slightly depressed, T1–4 apically narrowly lightened dark brown ( Fig. 90 ). Terga extremely smooth and shiny, almost without shagreen; tergal discs essentially impunctate, tergal margins with small dense punctures, punctures separated by 1–2 puncture diameters. T1 with scattered long whitish hairs, T2–4 with sparse short hairs laterally, apical hairbands absent. Fringe of T5 and hairs flanking pygidial plate golden; pygidial plate rounded triangular with slightly raised area centrally.

Male

Unknown.

Distribution

Southern Iran (Yasouj).
